I have to agree - I am using Hetres on a Rivendell Bleriot and if anything the ride on the Fuji is just as good with the Somas, in fact from my experience the lighter standard gauge tubing on the Fuji provides a more forgiving ride than the stiffer partially O.S. tubing on the Bleriot unless I have the tire pressures on the low side. So obviously frame geometry and type of tubing does contribute a noticeable difference, at least in my case.
